OverviewTOP

Oxymorphone is used to relieve pain. It belongs to the group of medicines called narcotic analgesics (pain medicines). It acts in the central nervous system (CNS) to relieve pain. Many of its side effects are also caused by actions in the CNS.

Oxymorphone extended-release tablets are used to relieve moderate to severe pain in patients requiring continuous, around-the-clock treatment for a long period of time, and should not be used if you need pain medicine for just a short time, such as when recovering from surgery. Do not use this medicine to relieve mild pain, or in situations where a non-narcotic medication is effective. This medicine should not be used to treat pain that you only have once in a while or "as needed".

When oxymorphone is used for a long time, it may become habit-forming (causing mental or physical dependence). However, people who have continuing pain should not let the fear of dependence keep them from using narcotics to relieve their pain. Mental dependence (addiction) is not likely to occur when narcotics are used for this purpose. Physical dependence may lead to withdrawal side effects if treatment is stopped suddenly. However, severe withdrawal side effects can usually be prevented by reducing the dose gradually over a period of time before treatment is stopped completely.

This medicine is available only with your doctor's prescription.

Proper UseTOP

Take this medicine exactly as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered. This is especially important for elderly patients, who may be more sensitive to the effects of pain medicines. If too much of this medicine is taken for a long time, it may become habit-forming (causing mental or physical dependence).

This medicine comes with a Medication Guide. Read and follow these instructions carefully. Ask your doctor if you have any questions.

It is best to take this medicine on an empty stomach, at least 1 hour before or 2 hours after a meal.

If you are using the extended-release tablets:

• Take the tablets whole, one tablet at a time, with enough water to ensure complete swallowing immediately after placing it in the mouth. Do not crush, break, cut, dissolve, lick, or chew it.
• While taking this medicine, part of the tablet may pass into your stools. This is normal and is nothing to worry about.

DosingTOP

The dose of this medicine will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of this medicine. If your dose is different, do not change it unless your doctor tells you to do so.

The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.

Missed DoseTOP

If you miss a dose of this medicine, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not double doses.

Use & StorageTOP

Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Keep from freezing.

Keep out of the reach of children.

Do not keep outdated medicine or medicine no longer needed.

Ask your healthcare professional how you should dispose of any medicine you do not use.

Oxymorphone can cause serious unwanted effects if taken by adults who are not used to strong narcotic pain medicines, children, or pets. Make sure you store the medicine in a safe and secure place to prevent others from getting it.

Before UsingTOP

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

AllergiesTOP

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

PediatricTOP

Appropriate studies have not been performed on the relationship of age to the effects of oxymorphone in the pediatric population. Safety and efficacy have not been established.

GeriatricTOP

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of oxymorphone in the elderly. However, elderly patients are more likely to have unwanted effects (eg, confusion, dizziness, drowsiness, nausea) and age-related liver, kidney, heart, or lung problems, which may require caution and an adjustment in the dose for patients receiving oxymorphone.

Breast FeedingTOP

There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

PrecautionsTOP

If you will be taking this medicine for a long time, it is very important that your doctor check you at regular visits for any problems or unwanted effects that may be caused by this medicine.

This medicine may cause serious allergic reactions, including anaphylaxis and angioedema. Anaphylaxis can be life-threatening and requires immediate medical attention. Call your doctor right away if you have a rash, itching, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth while you are using this medicine.

Oxymorphone may increase your risk of having serious breathing problems. Check with your doctor right away if you are having difficult or troubled breathing, irregular, fast, slow, or shallow breathing, pale or blue lips, fingernails, or skin, or shortness of breath.

Do not use more of this medicine or take it more often than your doctor tells you to. This can be life-threatening. Symptoms of an overdose include extreme dizziness or weakness, slow heartbeat or breathing, seizures, trouble breathing, and cold, clammy skin. Call your doctor right away if you notice these symptoms.

This medicine will add to the effects of alcohol and other CNS depressants (medicines that can make you drowsy or less alert). Some examples of CNS depressants are antihistamines or medicine for hay fever, other allergies, or colds, sedatives, tranquilizers, or sleeping medicine, other prescription pain medicine or narcotics, medicine for seizures or barbiturates, muscle relaxants, or anesthetics, including some dental anesthetics. Check with your doctor before taking any of the other medicines listed above while you are using this medicine.

This medicine may be habit-forming. If you feel that the medicine is not working as well, do not use more than your prescribed dose. Call your doctor for instructions.

Oxymorphone may cause some people to become drowsy, dizzy, or lightheaded, or to feel a false sense of well-being. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are dizzy, not alert, or lightheaded.

Dizziness, lightheadedness, or even fainting may occur when you get up suddenly from a lying or sitting position. Getting up slowly may help lessen this problem. Also, lying down for a while may relieve dizziness or lightheadedness.

Check with your doctor right away if you have anxiety, restlessness, a fast heartbeat, fever, sweating, muscle spasms, twitching, nausea, vomiting, diarrhea, or see or hear things that are not there. These may be symptoms of a serious condition called serotonin syndrome. Your risk may be higher if you also take certain other medicines that affect serotonin levels in your body.

Using this medicine for a long time can cause severe constipation. To prevent this, your doctor may direct you to take laxatives, drink a lot of fluids, or increase the amount of fiber in your diet. Be sure to follow the directions carefully, because continuing constipation can lead to more serious problems.

Before having any kind of surgery (including dental surgery) or emergency treatment, tell the medical doctor or dentist in charge that you are using this medicine. Serious side effects can occur if your medical doctor or dentist gives you certain other medicines without knowing that you are using oxymorphone.

If you have been using this medicine regularly for several weeks or more, do not change your dose or suddenly stop using it without first checking with your doctor. Your doctor may want you to gradually reduce the amount you are taking before stopping it completely. Withdrawal side effects may occur when the medicine is stopped suddenly because your body has become used to this medicine.

Tell your doctor if you are pregnant or plan to become pregnant while taking this medication. Using this medicine while you are pregnant may cause neonatal withdrawal syndrome in your newborn baby, which can be life-threatening. Tell your doctor right away if your baby has the following symptoms: abnormal sleep pattern, diarrhea, high-pitched cry, irritability, shakiness or tremor, weight loss, vomiting, or failure to gain weight.

Using too much of this medicine may cause infertility (unable to have children). Talk with your doctor before using this medicine if you plan to have children.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
